摘要： An optical fiber for use as a stub fiber in an optical fiber connector is disclosed. The optical fiber is configured with a segmented core that includes a single-mode segment with a step-index profile and at least one multimode segment having at least one alpha profile. A connector that employs the stub fiber can connect to both a single mode fiber and a multimode fiber.

摘要： A method of characterizing processed optical fiber ends using second-harmonic generation (SHG) is disclosed. The method includes sequentially irradiating micro-volumes within the end section with a focused laser beam of wavelength λL; sequentially detecting respective amounts the SHG light emitted from the respective micro-volumes; correlating the amounts of the detected SHG light with respective amounts of stress; and determining one or more optical properties of the end section of the optical fiber based on the amounts of stress. The optical fiber being measured can be held in a ferrule. The stress in the optical fiber end section can be due to processing the optical fiber end using laser and/or mechanical means.

摘要： A single-mode optical fiber for use as a stub fiber in an optical fiber connector is disclosed. The optical fiber is configured minimize the adverse effects of multipath interference (MPI) that can arise in a short, single-mode conventional stub fiber that has a large group index difference. The optical fiber is also configured to have a mode-field diameter that is substantially the same as that of single-mode optical fibers intended for use as field fiber in a mechanical splice connector, along with a cutoff wavelength λC≦1200 nm. An optical fiber connector that uses the optical fiber as a stub fiber is also disclosed.
